Only 3 stars – Kids Solar System - planets Review

My son loves this game however every time he backs out of it and opens it back up I have to restore the purchase. With this new update, none of the planets show up to do the puzzle. If I use memory I can put the invisible pieces where they belong but on the second screen, on every planet it's only the sun. When you put the letters in order its fir the planet I clicked on but still shows the sun. please fix then will change to 5 stars Thanks!
